It should not be necessary to do anything: both the items and the snippets should be immediately available.

My guess is that there must be something different about your Visual Studio set-up / configuration, and I'd like to figure out what it is.

First, let's figure out if the NakedObjects.Ide Nuget package did install the items and snippets. You should be able to check this in the trace in Output window, selecting the Package Manager option (imediately after the install). If not,
go look in the right directories. The items should be in e.g:

The folders you pointed to do not exist. I found the snippets in the project folder: "..\packages\NakedObjects.Ide.4.0.110.0\" and also noticed there's a PowerShell install script. Perhaps this has not ran after adding the packages?

Stef and I both work with Windows 7 also and the install works fine for us. As I understand it, in Windows 7, Users\MyName\Documents\Visual Studio 2010 and Users\MyName\My Documents\Visual Studio 2010 are aliases, so both should work. Having
copied them manually, can you get to them via either of those two paths? I'd like to get to the bottom of this as other people (e.g. Dan, above) must be hitting the same issue.

That does look like a culprit. I've raised this as an Issue to make sure we don't forget it - Stef and I are working flat-out on the Restful Objects API for Naked Objects up until Christmas, but we will return to addressing this and
other issues next month.
